Semantic HTML

<!-- Use semantic elements instead of generic divs -->
<header>
  <nav aria-label="Main navigation">
    <ul>
      <li><a href="/" aria-current="page">Home</a></li>
      <li><a href="/products">Products</a></li>
      <li><a href="/about">About</a></li>
    </ul>
  </nav>
</header>

<main>
  <article>
    <h1>Product Details</h1>
    <section aria-labelledby="specs-heading">
      <h2 id="specs-heading">Specifications</h2>
      <dl>
        <dt>Weight</dt>
        <dd>1.2 kg</dd>
        <dt>Dimensions</dt>
        <dd>30 x 20 x 10 cm</dd>
      </dl>
    </section>
  </article>
</main>

<footer>
  <p>&copy; 2024 Company Name</p>
</footer>

Use <nav>, <main>, <article>, <section>, <aside> instead of <div> for landmarks. Screen readers use these to navigate the page.

ARIA Patterns

function Modal({ isOpen, onClose, title, children }) {
  if (!isOpen) return null;

  return (
    <div
      role="dialog"
      aria-modal="true"
      aria-labelledby="modal-title"
      onKeyDown={(e) => e.key === "Escape" && onClose()}
    >
      <h2 id="modal-title">{title}</h2>
      <div>{children}</div>
      <button onClick={onClose} aria-label="Close dialog">
        <XIcon aria-hidden="true" />
      </button>
    </div>
  );
}
